The first specifically designed key to the interpretation of rock art of the American Southwest. Although the significance of the symbols will never be known for certain, educated guesses can be made. The Field Guide brings together 600 commentaries on specific symbols by over one hundred archaeologists, anthropologists, researchers, and Native American informant. Intended to be used in the field as well as a reference, the book includes a pictorial key at the beginning and is organized by tentative meaning where possible, or by description. Patterson emphasizes the tentative nature of the interpretaions and has included an index by neutral archaeological description as well as complete documentation of every excerpted comment.
